This is a lesson about the solar wind, Earth's magnetosphere, and the Moon. Participants will work in groups of two or three to build a model of the Sun-Earth-Moon system. They will use the model to demonstrate that the Earth is protected from...(View More) particles streaming out of the Sun, called the solar wind, by a magnetic shield called the magnetosphere, and that the Moon is periodically protected from these particles as it moves in its orbit around the Earth. Participants will also learn that the NASA ARTEMIS mission is a pair of satellites orbiting the Moon that measure the intensity of solar particles streaming from the Sun.(View Less)

Learners will investigate, discuss, and determine why humans have always explored the world (and now space) around them. Students determine these reasons for exploration through a class discussion. In the first activity, students use the Internet to...(View More) examine the characteristics of past explorers and why they conducted their exploration. They then examine why current explorers - including the students themselves - want to explore other worlds in the Solar System. By the end of the lesson, the students can conclude that no matter what or when we explore - past, present, or future - the reasons for exploration are the same; the motivation for exploration is universal.

The goal of this lesson is for students to understand how to plan a mission to another world in the solar system. They begin by discussing the path of a spacecraft traveling between planets, examining the journey from the Earth to Mars as an...(View More) example. In Activity 1, students determine the pros and cons for different ways we can explore another world, either by observing from the Earth or by sending a spacecraft to fly by, orbit, or land on the world. In Activity 2, the students plan a complete mission to explore another world in the Solar System. By the end of the lesson, the students come to understand that what scientists want to learn about an object determines how they plan the mission, but real-life constraints such as cost and time determine what actually can be accomplished.
